How Diamonds are Formed Cape Town Diamond

Diamonds are found at a depth of approx. 150-200km below the surface of the Earth. Here, temperatures average 900 to 1,300 degrees Celsius and at a pressure of 45 to 60 kilobars (which is around 50,000 times that of atmospheric pressure at the Earth’s surface). Under these conditions, molten lamproite and kimberlite (commonly known as magma) are also formed within the Earth’s upper
